Water Refill Points for Motorhomes in Europe

Q: Where can I refill my motorhome water tank in Europe?

At aires, campsites, some petrol stations, public fountains marked eau potable, and marinas. Aires with service points are your primary option, followed by campsites if you are booked in. Park4Night and Campercontact list water points for most European countries.

Q: Is European tap water safe to drink in a motorhome?

Generally yes in western and northern Europe. Tap water is safe in France, Germany, Belgium, Netherlands, Scandinavia, Austria, Switzerland, Spain and Portugal. Be cautious in rural southern Italy, parts of Greece and some Balkan countries. When in doubt, use the in-line water filter or carry bottled water for drinking.

Q: How often should I refill my motorhome water tank?

Plan to top up every 2 to 3 days of off-grid use, or every night if you are hooking up at a campsite. Two adults using a motorhome normally get through 30 to 50 litres a day, faster if you are showering on board. Never let your tank drop below 20 litres in case you cannot find the next refill.

Running the tank dry in the middle of Provence in August is a quick way to ruin a week. Good news: Europe is pretty well set up for water refills once you know where to look. Aires, campsites, marinas and the occasional village fountain will keep you topped up, and you rarely need to pay more than 2 EUR for a fill. Here is how to find them and what to watch for.

Where you can fill up

Aires service points

The most common source. Most French aires and German Stellplatze have a service point that dispenses fresh water alongside the grey-water drain. Some are free once you have paid the overnight fee, others want a 1 or 2 EUR jeton (token) from the barrier machine. A typical fill takes 5 minutes. Bring a 5-metre food-grade hose and a tap adapter (Hozelock and Gardena fittings cover most of what you will meet).

Campsites

If you are booked in, the service pitch at the gate usually lets you fill up for free on arrival or departure. Many ACSI sites also welcome day-stop fills for 2 to 5 EUR if the gate is open.

Petrol stations

A handful of big motorway services (Aires d'Autoroute in France, Autogrill in Italy, Raststatte in Germany) have a free water tap marked eau potable or Trinkwasser. It is not standard though, so do not bank on it. More reliable is the jet-wash bay: most have a hose marked potable and will let you top up for 1 EUR in the slot.

Public fountains

Village fountains in France, Spain and Italy are often drinkable. Look for eau potable (FR), agua potable (ES), acqua potabile (IT). If it says non potable, it is not. Carry a 10-litre canister and a flexible spout so you can fill it at a normal tap without blocking the square.

Marinas and beaches

Marina taps are usually accessible and drinkable. Some beach resorts have motorhome-specific taps near the shower blocks in summer. France and Portugal in particular are good for this.

Churches and cemeteries

Most French village churchyards have an outside tap for watering plants. Italians do the same. It is drinkable in almost all cases but ask if anyone is around, and never tie up the tap for 20 minutes during a funeral.

How to find them

Park4Night filters for water and waste. Turn the filter on and every icon on the map is a viable stop.
Campercontact does the same with slightly better European coverage in the north.
MyAires / Searchforsites both list service points independently of the overnight stay.
OpenStreetMap has a tourism=drinking_water tag that Organic Maps and OsmAnd both surface. Free and offline.

Campercontact users swear by its accuracy for water points in Scandinavia and the Netherlands. Park4Night has the edge in France, Spain, Portugal and Italy.

Is the water drinkable?

In most of western and northern Europe, tap water is fine to drink straight out of your motorhome tank. The usual suspects:

France, Germany, Austria, Switzerland, Belgium, Netherlands, Scandinavia. Tap water is safe everywhere. You can drink it without a second thought.
Spain and Portugal. Mains water is safe in cities and towns. Rural taps are sometimes unreliable, especially in Andalucia in late summer when the local reservoir gets low. Treat it as campsite-only drinking water in remote areas.
Italy. Safe everywhere on the mainland. The south and the islands sometimes have patchy pressure and a faint chlorine taste in summer.
Greece and the Balkans. Potable in the cities, suspect in the villages. Use bottled water for drinking when you are off the beaten track.
Eastern Europe. Generally safe. Poland and the Czech Republic are fine. Rural Romania and Bulgaria, carry bottled.

If you are unsure, fit an in-line carbon filter to your fill hose (the Nature Pure or AquaRoll filters are the common UK picks, around 30 GBP). Replace it once a season.

Practical tips

Carry 30 litres minimum in reserve. Most UK motorhomes have 100 to 120 litre tanks. Never let yours dip below about a quarter when you are on the road.
Food-grade hose, always. A garden hose taints the water fast. Buy a dedicated blue or white food-grade hose (roughly 15 GBP for 10 metres).
Universal tap adapter kit. Throw in a Hozelock to Gardena adapter plus a threaded tap connector. Covers 95% of European taps.
Sanitise twice a year. Once in spring, once at the start of the main trip. Milton tablets or a purpose-made tank cleaner. Do not skip this.
Avoid filling in direct sun. A full tank warming up under a dark roof turns into algae soup within a week. Park in shade and keep the tank cap on tight.
Never fill from a grey-water drain tap. It happens. Double-check the sign before you connect.

Common questions

Where can I refill my motorhome water tank in Europe?

Aires and Stellplatze are the mainstay. Add campsites, marinas, village fountains and some motorway services and you will rarely struggle. Park4Night and Campercontact mark every option on the map.

Is European tap water safe to drink in a motorhome?

In western and northern Europe, yes, straight from the tap. Southern and eastern Europe is more patchy, especially in rural areas. Fit an in-line filter and carry a few litres of bottled water for drinking if you are heading off the beaten track.

How often should I refill my motorhome water tank?

Two adults typically use 30 to 50 litres a day off-grid. Plan a refill every 2 to 3 days, or daily if you are hooking up at a campsite with unlimited water. Never let it drop below a quarter of tank capacity.
